Call your doctor. Explain your symptoms. You can try telling them how bad it is. It's impacting your daily life, or something like that. That's what I usually try with my neuro. He never gives me the steroids tho. Pretty much the only thing that gets me a steroid Rx is a vision problem, and then it's IV steroids (oral steroids are contraindicated for vision problems. Might make things worse)

Hopefully your neuro is more sympathetic than mine is. They might say it's a reaction to the medication. Maybe there's a few days that they'll make you wait to see if the problems level off, or go away?
